Q

definitions of abnormality - statistical infrequency

A

. when individual has less common characteristics, ex. being more depressed/less intelligent than most people
. ex. IQ/intellectual disability disorder
. average IQ is 100 in normal distribution, most people score range of 85-115 (68%), only 2% people score below 70
. people below 70 are seen as abnormal

Q

evaluation - unusual characteristics can be +ve. ; statistical infrequency

A

. limitation
. infrequent charac. can be +ve as well as -ve
. people don’t think someone is abnormal for having a high IQ or low depression score
. therefore SI can form part of the assessment/diagnostic procedures but never sufficient as sole basis of defining abnormality

Q

evaluation - cultural and situation relativism ; deviation from social norms

A

. limitation
. variation b/w social norms is diff b/w cultures/situs
. pers. fr. one cultural group may label someone from another group as abnormal using their standards than the persons
. even w/n one cultural context social norms differ
. ex. aggression/deceit in family is unacceptable but ok in business
. therefore shows difficult to judge deviation from social norms across diff. situs. and cultures

. rational/perceive ourselves accurately
. self actualise
. can cope w. stress
. have realistic view of the world

Q

behavioural approach to explaining phobias - acquisition by classical conditioning

A

. learning to associate something of no fear (NS) with something that triggers fear response
. watson/rayner; ‘little albert’, created phobia in 9 month baby
. had no fear to rat but when experimenters gave albert the rat they made loud noise
. noise = UCS wh. created UCR of fear, when rat and noise set close together NS stimulus became associated with UCS and both produce fear response now
. rat now CS that produces CR
. conditioning generalised to similar objects ie. non-white rabbit

Q

behavioural approach to explaining phobias - maintenance by operant conditioning

A

. phobias long lasting due to OC
. OC happens when beh. rewarded/punished
. reinforcement increases freq. of beh.
. mowrer; when we avoid phobic stimulus we successfully escape fear/anxiety that we would have experienced if remained
. reduction in fear reinforces avoidance beh. so phobia maintained

Q

evaluation - real world application of beh. appr. explaining phobias

A

. strength
. in exposure therapies
. phobias maintained by avoidance so exposure is good
. once avoidance beh. prevented it ceases to be reinforced by experience of anxiety reduction so avoidance declines
. therefore shows value of two process model bec. it defines a means of treating phobias

28
Q

evaluation - cognitive aspect of phobias ; beh. appr. explaining phobias

A

limitation
. does not account for cognitive aspects
. geared towards explaining beh.
. there is significant cog. component ex. irrational beliefs
. therefore shows 2 process model does not completely explain symptoms of phobias

29
Q

evaluation - phobias/traumatic experiences ; beh. appr. explaining phobias

A

strength
. link b/w bad experiences and phobias
. ex. little albert study
. jongh et al; found 73% people w. dentist fear experienced traumatic experience
. this confirms associated b/w stimulus and UR does lead to development of phobia

30
Q

evaluation - phobias/traumatic experiences 2 ; beh. appr. explaining phobias

A

limitation
. not all phobias fr. bad experiences
. not all bad experiences lead to phobias
. therefore shows association b/w phobia/experience not as strong as expected

31
Q

behavioural approach to treating phobias - systematic desensitisation

A

. behavioural therapy to reduce phobic anxiety thru classical conditioning
. counter conditioning involves ;
. anxiety hierarchy ; lost of situs, low levels to high
. therapist teaches pers. how to relax deeply
. reciprocal inhibition
. exposure to phobia in relaxed state, start at bottom of hierarchy and across sev. sessions
. successful when client stays relaxed

32
Q

behavioural approach to treating phobias - flooding

A

. immediate exposure to v. frightening situ.
. longer than SD
. stops responses quickly
. extinct CC
. learned response extinguished when CS encountered w/o US
. CS does not produce CR
. clients must give informed consent

33
Q

evaluation - evidence of effectiveness ; beh. treat. of phobia

A

. gilroy et al ; followed 42 people who had SD 4 spider phobia
. at both 3/33 months, SD g. less fearful than a control
. SD effective for specific p. social p. and agoraphobia
. therefore shows SD likely to help people with phobias

34
Q

evaluation - learning disabilities; beh. treat. of phobias

A

strength
. can help people with learning disabilities
. main SD alternat. not suitable for LDs
. LD people may feel confused/distressed by ex. flooding
. therefore shows SD often most appropriate treat. for LD people with phobias

35
Q

evaluation - cost effective ; beh. treat. of phobias

A

strength
. highly cost effective
. flooding can work in one session compared to 10 sessions of SD
. clinically effective / not expensive
. therefore shows more people can be treated at same cost w. flooding than w. SD or others

36
Q

evaluation - traumatic ; beh. treat. of phobias

A

limitation
. highly unpleasant experience
. surah et al ; fou, ppts/ therapist rate flooding +re stressful than SD
. dropout rates (attrition) 4 flooding higher than SD
. therefore suggests overall therapists may avoid this treatment

37
Q

cognitive approach to explaining depression - becks -ve triad

A

. cognitive vulnerability
. faulty info processing ; depressed people attend to -ve aspects of situ/ign. +ves, ‘black and white thinking’
. negative self schema ; self schema, package of info about yourself, pers. w. -ve self schema interpret info about themselves in -ve way
. negative triad ; person develops dysfunctional view of themselves bec. 3 types of -ve thinking:
. -ve view of world, future, self

38
Q

cog. approach to explaining depression - Ellis’s ABC model

A

. poor mental health res. fr. irrational thoughts
. irrational thought is any thought that interferes w. us being happy
. ABC model ;
. 1 . activating event A ; get depressed when experience -ve events, these trigger irrational beliefs
. 2 . beliefs B ; ‘musturbation’ , must always succeed/maj disaster when something doesn’t go smoothly have a ‘utopianism’ view of life and think everything must be fair
. 3 . consequences C ; active. event trigg. irrational beliefs, there r emotional/behavioural consequences

39
Q

evaluation - research support for becks -ve triad

A

. clark/beck; fou. cog. vul. +re common in depressed people b. also preceded the depression
. cohen et al; tracked 473 adolescents develop. and found those showing cog. vul. predicted later depression
. therefore shows association b/w cog. vul./depression

40
Q

evaluation - real world application for becks -ve triad

A

strength
. appli. in screening/treatment 4 depression
. cohen et al; concl. assessing cog. vul. allows psychiatrists to screen young people and identifies those at risk
. therapies can alter cognitions that make people vul. 2 dep.
. therefore means understanding cog. vul. useful in +re than 1 clinical setting

41
Q

evaluation - real world application of ABC model

A

strength
. psychological treatment of dep.
. rational emotive behavioural therapy REBT
. vigorously arguing with depressed person can alter irrational beliefs
. REBT can change -ve beliefs / relieve symp. of dep.
. REBT has real world value

42
Q

evaluation - reactive/endogenous depression

A

limitation
. ABC model on,y explains reactive depression not endogenous
. many cases of depression not trace to life events
. Ellis’s model can only explain some cases of depression
. therefore ABC model only partial explanation

43
Q

cog. appr. to treating depression - beck’s cog. therapy

A

. applic. of becks cog theory of dep.
. indentify -ve triad, thoughts must be challenged
. central component of therapy
. cog. therapy help clients test reality of their -ve beliefs
. ‘clients as scientist’ giving them h/w to record +ve things

44
Q

cog. appr. to treating depression - Ellis’s REBT

A

. REBT extends ABC model
. ABCDE model; D = dispute and E = effect
. empirical argument; disputing whether there’s actual evidence
. logical arguments ; vigorous argument

45
Q

cog. appr. to treating depression - behavioural activation

A

. depressed individual tend to avoid difficult situs and become isolated which maintains/worsens symptoms
. goal of BA to work w. depressed individual 2 gradually decrease avoidance/isolation so increases engagement in activities that have been shown 2 improve mood

46
Q

evidence 4 effectiveness of cog. therapy

A

strength
. supports effectiveness 4 treatment of dep.
. march et al; compared CBT 2 antidepressants
. 327 dep. adolescents; after 36 weeks 81% of CBT + 81% of drugs grp improved, combo grp. improved 86%
. CBT just as effective as drugs/cost effective
. therefore means CBT seen as 1st choice of treatment in public health

47
Q

cog. therapy suitability for diverse clients

A

. limitation
. lack of effectiveness for severe cases/LD people
. some people cannot engage bec. they’re so depressed
. sturmey; suggests psychotherapy not suitable 4 people w. LD
. therefore suggests CBT only appropriate for specific range of dep. people

48
Q

cog. therapy suitability for diverse clients counterpoint

A

strength
. CBT as effective as drug
. taylor et al; when CBT used appropriately it can be good for LD people
. CBT may be suitable for wider ranger of people than once thought

49
Q

evaluation - relapse rate; cog. appr. to treating depression

A

limitation
. CBT treatment of depression is high relapse rates
. CBT for dep. not long term
. Ali; 439 clients every month for 12 months found 42% relapsed w/n 6 months and 53% w/n a yr
. CBT may need to be repeated

50
Q

biological appr. to explaining OCD - genetic explanations

A

. genes involved in individual vulnerable to ocd
. lewis; 37% had parents w. ocd, 21% siblings w. ocd
. suggests ocd runs in families, gen. 2 gen.
. diathesis stress model; certain genes leaves some people +re likely 2 get mental disorder
. some environmental stress

51
Q

biological appr. to treating OCD - candidate genes

A

. genes that create vulnerability
. some are involved in regulating development of serotonin system

52
Q

biol. appr. to explaining OCD - ocd polygenic

A

. caused by combo of genetic variations together increasing vulnerability
. taylor; found up to 230 diff. genes may be involved
ex. genes for dopamine and serotonin production

53
Q

biological appr. to explaining ocd - diff. types of ocd

A

. 1 gene may cause ocd in person but diff. gene cause diff. ocd in another
. evidence suggests that diff. types of ocd may be result of particular genetic variations (aetiologically heterogenous)

54
Q

biological appr. to explaining ocd - neural explanation

A

. serotonin; low lev. causes low moods
. associated w. ocd

55
Q

evaluation - research support for genetic explanations; biological explan. for ocd

A

strength
. genetic explanations strong evidence base
. twin studies
. 68% identical shared ocd opposed to 31% non identical
. pers. w. family memb. w. ocd 4x +re likely 2 get ocd
. therefore suggests must be some genetic influence on ocd

56
Q

evaluation - environmental risk factors of biological expl. of ocd

A

limitation
. ocd not entirely genetic
. ex. cromer; half ocd clients experienced trauma
. therefore shows genetic vulnerability provides partial explanation

57
Q

evaluation - research support for biological expl. of ocd

A

strength
. antidepressants works only on serotonin, reduces ocd
. suggests serotonin may be involved in ocd
. sugg. bio. factors may also be responsible 4 ocd

58
Q

evaluation - research support for biological explanations of ocd

A

limitation
. co-morbidity
. depression probably involves disruption 2 action of serotonin
. therefore means serotonin not relevant 2 ocd

59
Q

biological approach to treating ocd - SSRIs

A

. particular type of antidepressant drug
. works on serotonin system in the brain
. SSRIs effectively increase levels of serotonin in the synapse and continue to stimulate the postsynaptic neurone
. for 3-4 months daily use 4 SSRIs 2 have impact on symptoms

60
Q

biological approach to treating ocd - combining SSRIs w. other treatment

A

. drugs used alongside cog. beh. therapy
. drugs reduce persons emotional symptoms
. so can respond to CBT +re effectively

61
Q

biological approach to treating ocd - alternative to SSRIs

A

. after 3-4 months w. no effect dose can increase
. can combine w. other drugs
. alternatives may work :
. tricyclics ; +re severe side effects, reserve 4 SSRIs
. SNRIs ; second line of defence

62
Q

evaluation - evidence of effectiveness; biological treatment of ocd

A

strength
. clear evidence shows SSRIs reduce symptoms severity/ improve quality of life
. 17 studies; compared SSRIs w. placebos
. all 17 showed improvement w. SSRIs
. drugs appear to be helpful 4 most w. ocd

63
Q

evaluation - evidence of effectiveness counterpoint ; biological treatment of ocd

A

limitation
. drugs may not be most effective
. shapinahis et al; concluded both cog./behavioural therapies were +re effective than SSRIs in treatment
. therefore means drugs may not be best treatment

64
Q

evaluation - cost effective/non disruptive ; biological treatment of ocd

A

. drug treatments r cheap, 1000s of tablets can be manufactured in the time of 1 session
. drugs good value 4 public health
. SSRIs non disruptive
. drugs popular w. people and doctors

65
Q

evaluation - serious side effects ; biological treatments of ocd

A

limitation
. small minority have no benefit
. SEs usually temporary but can be distressing
. therefore means some people have reduced quality of life as result of taking drugs/may stop taking them
